taining means.y The inner edges of the foot portions 35 and 36 abut the. shoulders 8 and 9'. It

will' thus be understood that the projections 19 and 20, shoulders 33 and 34, and theigfoot 'portions 35 and 36 abutting the shoulders 8 and 9 serveadequately to prevent longitudinal displacement of the parts H and B. In addition, the lugs 21 yand 22r prevent bulging of the side walls 10 andll.

The upper margins of the side walls 10 and 11' and the cylindrical endwalls- 23 and 24 are provided .vvith continuous external iianges 39 and.

40, and the side walls 1G 'and 11 are, in addition;

inwardly directed reinforcingflanges 41 and 42 which. serve to overlie the trunnions 43 and 44 of. theV roller .R andprevent the provided i with latter` from jumping `out ofthe housing when. in operative position` 1- Drain openings are provided at the ends of the housing by removing portions rof the cylin-L drical walls 23 and 24 in forming, the casting I-I',

, From the4 foregoing ,it vwill beunderstood that,

inthe provision of the housingghavingseparable parts,gin the event that the uppercasting H becomes fractured or otherwise damaged .in` use, this may be readily removed and a new upper casting substituted. The housings and` base portions are..interchang eable and permit of the .re-

newal. of the housingvr without the necessityV of renewing fthe base portion, which vmakes for` economy in maintenance. y
